Reverse hitting preparation technology of non-facing layer prefabricated wall body

Abstract

The invention discloses a reverse hitting preparation technology of a prefabricated self-insulation wall body. The wall body comprises a concrete wall body, an insulation board and a cement mortar layer protective layer, wherein the insulation board is arranged at the outer part of the concrete wall body; the insulation board is provided with a protective layer; and the cement mortar layer protective layer is arranged at the outer part of the insulation board. The prefabricated self-insulation wall body is produced through an insulation board reverse hitting construction technology, and connecting pieces of outer hinge plates in an original sandwich structure and the interior and exterior are discarded, so that the cost is greatly reduced, the production efficiency is improved, selfweight of buildings is decreased, and large-scale popularization of the prefabricated buildings is guaranteed.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to the field of manufacturing method, design and installation of a novel prefabricated wall. Background technique [0002] As the largest developing country, my country's energy consumption per unit of GDP is more than twice the world's average level. Faced with an increasingly severe energy security situation, the country is vigorously promoting energy conservation and emission reduction in various fields. Building energy consumption accounts for 20-30% of my country's total energy consumption, so building energy conservation is particularly important. The latest building energy-saving standard is that the northern regions such as Beijing, Tianjin, Shandong, Hebei, Xinjiang and other provinces have achieved 75% energy-saving standards. Most of the urban residential buildings in most areas require 65%, and very few areas require 50%. Due to the late development of buildi...

Problems solved by technology

However, at present, the prefabricated wall generally adopts a sandwich structure. This structure is to connect the 5-8cm thick concrete plate on the outside of the insulation board with the concrete of the main structure through the connector passing through the insulation board. The sandwich structure There are cumbersome production, high cost, and low safety system. There is no implementation standard for the connectors used to fix the outer 5-8cm thick concrete slab, the quality is difficult to guarantee, and a large number of cold bridges are formed. At present, all rely on imports, and the cost is high. No less, it is difficult to promote the current prefabricated buildings, and the incremental cost remains high
